Summary:

The National Hospital Discharge Survey (NHDS) collects
medical and demographic information annually from a sample of hospital
discharge records. Variables include patients' demographic
characteristics (sex, age, race, marital status), dates of admission

Information on hospital characteristics such as bedsize, ownership,
and region of the country is also included. The medical information is
coded using the INTERNATIONAL CLASSIFICATION OF DISEASES, 9TH

Methodology

Sample:
The redesigned (as of 1988) NHDS sample includes with
certainty all hospitals with 1,000 or more beds or 40,000 or more
discharges annually. The remaining sample of hospitals is based on a
stratified three-stage design. The first stage consists of selection
of 112 primary sampling units (PSUs) that comprise a probability
subsample of PSUs used in the 1985-1994 National Health Interview
Surveys. The second stage consists of selection of noncertainty
hospitals from the sample PSUs. At the third stage, a sample of
discharges was selected by a systematic random sampling technique. For
1996, the sample consisted of 525 hospitals. Of these, 18 were found
to be ineligible. Of the 507 eligible hospitals, 480 hospitals
responded to the survey.
